To all whom, it ntcvy concern.-

Be it known that 1, WILLIAM FRANK, a citizen of the United States, and aresident of Guttenberg, in the county of Hudson and State of New Jersey,have invented a new and Improved Dough-Rolling Machine, of which thefollowing is a full, clear, and exact description.

This invention is an improved machine for rolling or molding dough orother plastic materials into spherical or other convenient shapes, theobject of the invention being to simplify the construction of machinesof this character and render the machine more effective in operationthan those of this class hitherto devised; also, to so construct themachine that it can be readily taken apart for cleaning or otherpurposes.

To this end the invention consists of a grooved wheel suitably journaledon a machine-bed and meshing with a grooved segment partiallysurrounding its circumference and concentrically arranged thereto, oneend of the segment acting to receive the dough for shaping it and theopposite end discharging it in a spherical or other desired shape. Thissegment is made in halves in order that it may be readily stripped fromthe wheel to clean it and is adjustably fixed to the frame of themachine by parallel beams, upon which the grooved wheel is journaled,acting to clamp the segment at each side.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal vertical central section of the machine. Fig.2 is a plan view of the same, and Fig. 3 is a transverse sectional viewof the wheel and its cooperative segment members.

The invention comprises a bed 1, suitably supported, upon which arearranged two parallel beams 2. Substantially at the center of the topface of these beams are secured journal-boxes 3, in which is ournaled ashaft 41, having fixed to it between the beams 2 a grooved wheel 5 bymeans of a set-screw 6, and at its outer end a pulley 7 for driving thegrooved wheel from any source of power, or, if preferred, the shaft4 maybe provided with a hand-crank. The wheel 5 is constructed, as best shownin Fig. 2, with a semicircular groove in its periphery, lined with acanvas covering 8, fastened to the periphery with glue or other adhesivematerial.

At each endof the beams 2 a bolt 9 passes through alining apertures inthem, and said bolts have threaded on their outer ends thumb-nuts 10,designed to draw the beams together and clamp a segment 11, partiallysurrounding the Wheel, in adjusted relation.

The segment 11 is made in two longitudinal halves 12 and 13, each ofwhich is provided with a groove 14 on its inner face constituting aquarter of a circle, so that when the halves of the segment are placedtogether and outer periphery and are clamped in adjusted relation to thewheel after they have been applied to it by the action of the thumb-nuts10 drawing the beams 2 in contact with its faces. The beams .2 are thenfastened to the bed by screws 16 As shown in Fig. 1, after the machineis assembled the entrance-opening between the wheel and segment isprovided with a funnel 17, enabling the dough to pass freely to themachine, and a discharge-funnel 18, through which the dough is ejected.The groove in the segment adjacent to the discharge-opening is slightlyenlarged, as shown at 19, for the purpose of permitting the dough tofreely pass upward at this point.

In the operation of the machine after it has been properly put togetherthe wheel 5 is set in motion through the action of the pulley 7, and theoperator, standing at the front of the machine, feeds dough of asuitable size into the funnel 17 which the wheel acts to roll in aspherical shape as it draws it through the segment. The canvas on thewheel acts to increase the friction between it and the dough, renderingthe machine positive in action. After the spheres of dough pass into thefunnel 18 they are removed by the hand of the operator.

Although I have described the invention in detail, it is to beunderstood that the scope thereof is limited by the annexed claims only.7

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. In adough-rolling machine, two longi drawing the beams together.

2. In a dough-rolling machine, a revoluble grooved wheel, a segmentpartially surrounding the circumference of the wheel having a taperinggroove therein, said segment being constructed inhalves removablysecured together, and means forholding the segment in adjusted relationto the wheel.

3. In a dough-rolling machine, a grooved wheel, a grooved segmentpartially surrounding the circumference of the wheel, said segment beingconstructed of longitudinallydivided parts, and means for holding saidsegment in adjusted relation.

4. In a dough-rolling machine, a bed, two longitudinal beams secured tothe bed, a grooved wheel j ournaled on the beams, a grooved segmentpartially surrounding the circumference of the Wheel, means for drawingthe beams together to clamp the segment in adjusted relation betweenthem, and means for securing the beams to the bed.

5. In a dough-rolling machine, two longitudinal beams, a grooved wheeljournaled on said beams, a grooved segment partially surrounding thecircumference of the wheel and adapted to be clamped in adjustedrelation between the beams, said segment being longitudinally divided inparts which are removably secured together, and means for operating thewheel.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM FRANK.
